Remarks

It is possible to specify expressions for unbound columns via the TreeListColumn.UnboundExpression property. An end-user can edit these expressions at runtime via an Expression Editor, which can be invoked via a column’s Menu (see the TreeListColumn.ShowUnboundExpressionMenu topic). The Expression Editor contains a field list providing access to all available columns. If the ShowInExpressionEditor property is set to false, a column will not be available in the field list.
